As Kyle Cavaliere drove down I-75 in Naples,Indexbit Exchange Florida an object in motion caught the corner of his eye.

He turned to look. It was an airplane, and something was terribly wrong.

"After a couple of seconds I realized it was not going up, it was actually going down," Cavaliere told the Naples Daily News in an email.

The plane, a Bombardier 600 private jet, crashed on top of a white pickup truck two cars in front of him, Cavaliere wrote. It spun out of the control and burst into flames, coming to rest off the shoulder of the highway.

'Are they alive?'

"Is there anybody else in there?" he shouted.

"Yes, our pilots!" one of the survivors responded.

"Are they alive?"

"I don't know!"
